* Year of the S-10: The engine and head design changed over the years the S-10 was produced.
* Engine Type: The S-10 used various engines (4-cylinder, V6). Even within engine families (like the 4.3L V6), there were variations over the years.
* Head Bolt Material: The head bolts themselves may be different materials (e.g., standard steel vs. upgraded materials) requiring different tightening procedures.
* Head Gasket Type: While less directly influential on the *head bolt* torque, the gasket type might influence the overall head tightening procedure.
To find the correct torque specifications, you MUST consult a repair manual specific to your vehicle's year, engine, and any other relevant specifics. These manuals are available from several sources, including:
* Your vehicle's owner's manual: It might have a summary.
* Online repair manual websites: Sites like Chilton, Haynes, and others sell online access or downloads.
* A local auto parts store: Many stores have access to repair information databases.
* A professional mechanic: They will have access to the proper information.
Attempting to torque the head bolts without the correct specifications is extremely risky and could lead to engine damage, including cracked heads or warped heads. Using the wrong torque can cause a head gasket leak, which can lead to serious engine failure. Don't guess; get the correct information.
